FRONT ACCESS DOOR ADJUSTMENT AND SEAL

When handling ceramic fibre always follow the local regulations regarding such materials, including the
use of breathing apparatus, suitable body protection and protective gloves.
The front access door is held in position by four swivel bolts A fitted with M48 hexagon nuts B.
The hinge side is secured by a parallel hinge system allowing the door to move away from the
front face of the boiler when turning the hinge nuts B anti-clockwise, but still secures the door to
the hinge pin.
The swivel bolts A on the latching side can be moved out of their securing slots once the nuts are
undone. In order to seal the door fully around the circumference, it is important to ensure the door
is parallel to the front sealing face of the boiler before finally tightening the securing nuts to effect
a seal. When opening and closing the door always slacken and then tighten all four nuts B, not
just the two on the latching side.
The door seal utilises a 25 mm x 35 mm square section glass rope which is glued into an angle
section welded into the perimeter of the door. Over a period of time the glass rope will lose its
ability to deform sufficiently to take up the irregularities between the door and sealing faces, which
may result in a gas leak, if leakage occurs the boiler should be shut down and the seal replaced.
To remove the seal, locate the joint (usually at the six o'clock position). Prise out one end and
using a chisel or similar to break the glued joint, pull out the remainder of the seal.
